Historically, storage has been a challenge for video system designers and installers, with requirements rising along with camera resolutions. The addition of big data, the Internet of Things (IoT), integrated systems and IT applications to the mix have multiplied storage needs exponentially.
Another thing contributing to increased storage demands is the expanded use of video surveillance for more than just security. Video deployments are growing rapidly because organizations recognize the value of video data for a wide variety of purposes, including operational efficiency, situational awareness, risk mitigation and even marketing and merchandising.
According to Brian Carle, director of product strategy, Salient Systems, Austin, Texas, there are several factors affecting storage platform selection: scalability, speed, storage management, fault tolerance, reliability, and cost. For more distributed or lower camera count systems, the scalability and speed that comes with platforms such as storage attached networks (SANs) are generally unnecessary.
Most storage technologies provide a suitable speed for the needs of video surveillance. The notable exception is tape systems, which may be considered for deployments requiring low-cost, long-term, onsite storage such as some deployments in the cannabis industry, Carle says.
“If real-time access is required, then tape may not be ideal. Accessing archived video on tape may require a manual import process due to the latency associated with robotics accessing a tape which contains the appropriate data,” he says.
